is to provide an improved arrangement of siphon having novel means forreleasing the air in the bell used herewith thus providing for rapidflushing.

A third important object of the invention is to provide a novelconstruction of siphon having a gas seal to prevent passage of air fromthe bowl into the tank when the tank is full.

With the above and other objects in view,- the invention consists ingeneral of certain novel details of construction and combinations ofparts hereinafter more fully described, illustrated in the accompanyingdrawing and specifically claimed.

, In the accompanying drawing like char-.

acters of reference indicate like parts in the several views, and:

Figure 1 is a section through one end of a tank showing the device inposition therein; Figure 2 is a vertical section through the siphoningdevice;

Figure 3 is a detail section similar to Figure 2 with the outer casingomitted and showing a modification of the invention.

' As here shown, there is provided a tank 10 of ordinaryconstructionhaving the siphoning device located therein.

In the form shown in Figure 2, this siphoning device includes a nipple11 in the bottom of the tank 10 and secured thereto by a nut '12. Thisnipple is for connection of the usual closet L (not shown). At one sidethis nip ple is extended and is made hollow to provide an air chamber 13from whence a pipe 14: extends up above the water level 15 in the tank.

A housing 16, closed at the top and extending above said water line isfixedly supported on the flange of the nipple by legs 17 so that watermay have free access to the interior. The upper part of the nipple isshouldered inwardly to provide a reduced opening 1930. Serial No.441,993.

through which fits an inner fixed siphon tube 18 having an outer member'19 fixed by its bottom edge around the upper part so as to provide achannel 20. In this channel 20 fits theinner wall2l of a double walledbell which has an outer wall 22 surrounding the tube 19 in spacedrelation thereto. '-The walls 21 and 22 are connected at their upperends by a frusto-conical annular closure 23 which sup-- ports aninverted frusto-conical annular plate 2a the inner edge of whichoverhangs the, opening of the tube 18.

Pivoted at its middle portionto lug25 I projecting from one of the legs17 is a-lever 26 which has its inner end connected to the bottom of thewall 22. Extending through the. wall of they tank 10 above the waterline is an operating lever 27 having its inwardly projecting endconnected by a wire 28 to the remaining end 03": the lever 25. V

In operation, the tank isnormally full and thebell'is in the dotted lineposition of Figure. 2. To flush the closet, the outer endfof the lever'27 is depressed which pulls this bell down until the water flows overthe guide plate 24 into the tube 18 and starts siphonic action. Thisaction draws, by aspiration, the air out from'between the walls 21' and22 and the'channel 20 so that the bell drops to its lowest positionas'shown in Figure 2 and the tank is rapidly emptied. When the tank isempty, the space between the wlalls2-1. and 22 again fills with air sothat, as thewater rises in the tank through the usual inletpipe (notshown) the bell will lift due tothe trapped air and assume its'normalposition.

In the form shown in Figure 3, the tube, 8

18 is replacedjby a tube 29double walled at its upper partpth'e outerwall being indicated at 30. The space between thel'bo'dy of the tube andthis wall is closed at the topr'aslat 31, The bell ofFigure 2 isreplaced-in this form by a bell having an inner wall 32 and an outerwall33 connected at their topedge's by 'aninverted frusto-conical plate34. The inner wall has at its bottom'an inwardly extending flange 35from the inneredge of which rises awall 36 which lies between the t ple,andlfa' pipe leadi'ng 'fronrsaid air. cham- Connected at its top bya-plate 38 to the innerlw all' 320i the bell, V e ITheotherarrangements' are the same as in the first form and theoperation is likewise the same, this form having a double air trap sothat the flotation isincreased.
